MAX6309UK27D2-T

Supervisors Overview

The MAX6309UK27D2-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of 1V to 5.5V and features factory-programmed reset thresholds for 2.7V and 5V inputs. The device provides an active low, push-pull output with a manual reset input capability. It includes a fixed reset delay time of 1.4ms and consumes 8µA of operating supply current. The component is housed in a SOT-23-5 surface-mount package and supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Asserts system reset when monitored voltages fall outside programmed thresholds
• Includes manual reset input for external control
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm pinout and threshold configuration. Confirm RoHS compliance status as indicated by the part number variant. Check availability through authorized distributors as stock levels vary.

Supervisors Selection Notes

Select this component for designs requiring dual-supervision of distinct voltage rails. Ensure the 2.7V and 5V thresholds align with target power rails. Verify that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These devices are optimized for portable electronics due to low current consumption and small footprint.
